Akutagawa gets a new partner, Lilith. Her goals are unknown to him, but he decides to follow the orders from his boss and works with her. In one mission, they have an encounter with the weretiger Atsushi from the armed detective Agency... Yaoi. Don't like it, don't read it. I don't own the characters, they belong to the author of Bungou stray dogs. I only own the story line and the OC Lilith :)
